DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

LSP diagnostics accept string severities

You'll notice
Useful3 Signal0
IDE Integration

IDE diagnostics that label severity with a word instead of a number now show up instead of vanishing.

What

Diagnostics from the IDE MCP server that report severity as a word rather than a number are now understood instead of being dropped.

Details
  • a new lookup lowercases the string and maps error, warning, info, information and hint to the canonical form
  • non-strings and unrecognised values yield no severity
  • the mapping table is absent from the previous build
Evidence

information

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
